Going back to what I said about the Honeywell valve... is it me, or is the boby newer than the head and spindle plate?
The valve isn't the original but I would hardly say it was new.
And as for the pump.... 13/14 years I have been doing this, and I can't remember buying a new Grunny that looked like that.
Anyway - TF1 are crap.
Suggestion 4 is b*****t.
Suggestion 5 is also boolax - external corrosion on a rad in a bathroom has no bearing on what is going on inside. Especially if said rad is next to the bog.
How modern is this control panel?
You would possibly benefit from an AAV on the heating pipe just after the pump as your vent pipe (from what I can see) is on the negative side of the pump, air isn't likely to go up that naturally.
If the rads heat up nicely, then the pump is fine.
The valve above the pump is pretty new and I would guess the pump was changed as well and not very long ago. Dont you remember when that was done?
This friendly plumber seems very keen to change a lot of bits, most of which I dont expect to provide any/much improvement.
Perhaps making a £190 job into a £500 job!
I would usually use x800 as a cleanser as its faster ( 2-4 hours ) and a lot stronger!

If the system is drained then it's up to you really. The pump could live longer, it could die next week. But the guy should be able to tell you if the valve is guffed or not.
These smart pumps are a complete con....or at least the claimed savings.
Magnetic inline filters as a concept are very good though. Every tf1 we have fitted has leaked. Spirovent have been been fine but the Magnaclean is the easiest to clear and catches the most muck.
Wilo get a bad rep, but I've not had any issues with them. Grundfos are better though.
Stick with honeywell.
As to which filter. ?..
It's down to personal preference again.
Magnaclean did have an issue years ago but they have been through several revisions.
If you plan to clean it yourself then definitely the Magnaclean.
All i know is i have tried the others and have always gone back to Magnaclean.
The Spirovent will never leak, but cleaning it is a performance for the homeowner as it involves buckets and hoses.
For Price the wilo is fine. Otherwise get the cheapest Grundfos you can find.
Personally I would have a more expensive, simpler grunny over a cheaper and cleverer wilo. But if I was being charged cost+20% I would be happy with either.
